MOLDED DEVICE.

Application filed April 1, 1918, Serial No. 225,890.

To 'all whom it may concern:

Be; it known that I, WALTER SODERLING, a citizen of theUnited States, and a resident of Reading, in the county of Berks and State of Pennsylvania, have invented an Improvement in Molded Devices, of which the following is a specification.

This invention relates to molded articles,

and with regard to certain more specific features, to a support for a telephone transmitter and method of supporting a transmitter.

Among the severalobjects of the invention may be noted the provision of a convenient and inexpensive holder for a transmitter, so constructed as to exclude extraneous sounds and yet in no way impede the wearers breathing; and the provision of a method for supporting the transmitter in such a way as to permit the wearer to speak into the transmitter without requiring the use of either of his hands, and at the same time to exclude extraneous sounds from the transmitter. obvious and in part pointed out hereinafter. The invention accordingly consists in the features of construction, combinations of elements, steps and sequence of steps, and arrangement of parts which will be exemplified in the structure hereinafter described and the scope of the application of which will be indicated in the accompanying claims.

In the accompanying drawings, in which is shown one of various possible embodiments of this invention,

Figure 1 is a front elevation of the article itself. 1

Fig. 2 is a front elevation of the article, showing a transmitter and band associated therewith as the several parts appear when in use. p

Fig. 3 is a side elevation of Fig. 2. i

Fig. 4 is a longitudinal vertical section.

Similar referencecharacters refer to corresponding parts throughout the several views of the drawings.

Referring now to the accompanying drawings, there is illustrated at 1 a molded article, in this case of rubber, made in a single piece and comprising two portions. The rear portion 3 is approximately triangular in cross-section and tapers outwardly toward the rear and terminates preferably in a thin Other objects will be in part Specification of Letters Patent.

or feather-edge 4 of such contour that it adapts itself readily to the features of the wearer, a recess 6 being provided at the top to fit about the wearers nose, the lower edge 7 fitting preferably between the wearers mouth and chin, as indicated diagrammatically in Figs. 2 and 3. The front end of this rear portion comprises a'vertical plane or flange member 9, covering the entire front surface of this rear portion except for a round aperturell communicating with the front portion 13 of the article. This front portion is approximately cylindrical in shape, with a diameter somewhat larger than the aperture 11, and is provided with a plane or flange member 14 at its. front or outer surface. This front flange 14' is apertured as at 16 and extends outwardly beyond the outer surface of the cylindrical part 13, to an approximately elliptical shape, and is pierced as at 19, for a purpose hereinafter is smaller than theinner diameter of the cylindrical part 13, but is larger than the diameter .of the aperture 11.

The front portion of the article is shaped to receive a telephone transmitter, of any suitable type, and the exact contour of the front portion varies naturally according to the dimensions of the transmitter with which it is intendedto be used. The embodiment of the article that is illustrated in the drawings is proportioned to receive a transmitter of a fiat cylindrical shape, and the aperture 16 at the'front of the article is large enough and the flang 14 flexible enough, so that the transmitter can be inserted and removed through this aperture- The inner aperture 11, however, is small enough to prevent the transmitter from passing therethrough. When the transmitter, which is indicated conventionally at 21 in Figs. 2 and 8, is placed in position within the cylindrical part 17 of the front portion, a plate or other retaining l1 :5: I lessees vided in the rear portion 3 to permit the entrance and exit of air for breathing, without, however, admittmg extraneous noises to an extent that would disturb the clearness of transmission of thewearers voice to the te ephone circuit. The apertures 29 are of proper size to insure breaking up of sound vibrations that would interfere with the transmission of the wearers voice to the transmitter.

An additional aperture in the rear portion 3 may be provided to supply a suitable gas to the wearer in addition to air.

An absorbent material is preferably provided at the rear ofthe transmitter'to prevent moisture reaching the transmitter, and around the inside of the rear portion 3 to absorb moisture of the breath.

It will thus be seen that the several objects of the invention are achieved, and other advantageous results attained.

As many changes could be made-in the above construction and many apparently widely difierent embodiments of this, invention could be made without departing from the scope thereof, it is intended that all mat- V ter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense. V

I claim:

- l. A molded article having a flaring portion adapted to fit about the nose and mouth, the walls thereof converging in a forward direction and terminating in an aperture, a second portion integral with the first and adapted to contain a telephone transmitter, the diaphragm of the transmitter registering substantially with the aperture in the first portion whereby the voice of the'wearer is confined within the first portion and directed toward said diaphragm'to the exclusion of extraneous sounds, the second portion being provided with an outer flange smaller than the transmitter but sufliciently flexible to permit the insertion and removal of the transmittertherethrough, and means secured to the outside of said flange to retain the transmitter in position.

2. A molded article combining a portion adapted to fit the nose and mouth and havinga feather. or tapered edge to fit closely to the wearers face, a portion adapted to hold a telephone transmitter, and absorbent material positioned to absorb moisture of the breath, and to prevent moisture reaching the transmitter.

In testimony whereof I have signed my name to this specification this 29th day of March, 1918.

- WALTER so-DERLiNG.
